  • StudyIB chemistry is an amazing resource. I like that it is condensed but also informative; I much prefer it to the textbooks! I only used StudyIB notes for my mocks and am also planning on using it for my final exams. I really recommend it!

  • This is genuinely the holy grail of IB chemistry resources. IB is very stressful and keeping on top of your content and revision is difficult. This website has amazingly clear explanations for all syllabus points, it's so good that I haven't use my actual notes for revision. The multiple-choice question that are available on this website is brilliant for testing the breath of your knowledge and super convenient to do on the app on the train or the bus.
